General Description
The VHC595 is an advanced high-speed CMOS Shift
Register fabricated with silicon gate CMOS technology.
It achieves the high-speed operation similar to equiva-
lent Bipolar Schottky TTL while maintaining the CMOS
low power dissipation.
This device contains an 8-bit serial-in, parallel-out shift
register that feeds an 8-bit D-type storage register. The
storage register has eight 3-STATE outputs. Separate
clocks are provided for both the shift register and the
storage register. The shift register has a direct-overriding
clear, serial input, and serial output (standard) pins for
cascading. Both the shift register and storage register
use positive-edge triggered clocks. If both clocks are
connected together, the shift register state will always be
one clock pulse ahead of the storage register.
An input protection circuit insures that 0V to 7V can be
applied to the input pins without regard to the supply
voltage. This device can be used to interface 5V to 3V
systems and two supply systems such as battery
backup. This circuit prevents device destruction due to
mismatched supply and input voltages.
